New-gen LFP bus batteries final 15 years, CATL claims—20% longer
CATL claims a 22% enhance in vitality density by quantity, and 175 Wh/kg by weight
Superfast Charging Version goes as much as 70% in quarter-hour
Chinese language battery provider CATL has unveiled a brand new battery pack for electrical buses designed to tolerate the pains of public-transit use.
The CATL Tectrans Bus Version pack, formally revealed at IAA Transportation 2024 in Germany, is designed for longer-distance passenger buses, and it has an vitality density of 175 watt-hours per kg—larger than different lithium iron phosphate (LFP) bus batteries.
It is one in every of CATL’s new Tectrans battery packs for vans and buses that it claims will last as long as 15 years—a 20% extension primarily based on tech enhancements—or 1.5 million km (almost 1,000,000 miles), in response to a presentation, with a guaranty “that covers all the automobile lifecycle,” Aleksej Krükov, the corporate’s chief engineer of abroad enterprise, mentioned Monday on the present. Additional, a Lengthy Life Version was pegged at 15 years or 2.8 million km (1.74 million miles), with battery swapping choices.
In the meantime, very quick charging is a key a part of the merchandise, too. In a Superfast Charging Version, CATL claims a 70% cost in simply quarter-hour—a feat that, for fleet operators would require megawatt charging.

CATL instructed present attendees that it’s at present in talks with 13 automobile producers to make use of the Tectrans Bus Version battery in as much as 80 fashions, in response to CnEVPost, though it is unclear if any of those can be offered outdoors of China.
The brand new-generation battery packs vary as much as 600 kwh. They make use of a brand new high-press-density cathode design that helps result in these packs’ 22% enhance in vitality density by quantity. Within the Superfast charging version CATL has additionally labored to equalize temperatures throughout the pack.
The battery firm has a variety of potential prospects, as many corporations already construct and promote electrical buses world wide. Within the U.S., China’s BYD has made numerous electrical buses, as has specialist corporations like Proterra and established producers of internal-combustion autos. Mercedes-Benz has even constructed buses with solid-state batteries that marked the primary use of that tech in a manufacturing automobile.

CATL has lengthy been a serious participant within the passenger-car EV battery enterprise, and has developed cell-to-pack tech as an alternative choice to typical battery packs that the corporate has claimed can ship an influence benefit. It is now focusing extra on commercial-vehicle purposes with the Tectrans model, which launched in July with two batteries for business vans, together with a long-range model and a fast-charging model that may be charged to 60% in as little as 12 minutes, in response to CnEVPost.
Whereas electrical vehicles get many of the consideration, electrical vans and buses are an essential a part of the emissions-reduction equation. A 2021 research estimated {that a} shift to electrical vans and buses may save 57,000 lives by 2050 by lowering air air pollution and its related unfavourable well being results.
